Embodiment
Describe the related circuit breaker of embodiments of the present invention in detail based on accompanying drawing below.In addition, the present invention is not limited by these execution modes.
Execution mode 1
Fig. 1 is the front view that represents the brief configuration of the related circuit breaker of embodiments of the present invention 1.Circuit breaker 50 comprises airtight casing 1 and operating means 8 and forms.The inside of airtight casing 1 is accommodated with the first explosion chamber 2, the second explosion chamber 3, bonding conductor (connecting portion) 4.In addition, Fig. 1 omits and represents the internal structure of Liao Ge explosion chamber 2,3, the internal structure of operating means 8.
Airtight casing 1 has the first chest portion 5, second chest portion 6 of surrounding of encirclement the second explosion chamber 3 and the link box body 7 of the surrounding of encirclement bonding conductor 4 of the surrounding that surrounds the first explosion chamber 2.The airtight casing 1 of circuit breaker 50 is supported by casing support foot 10, is arranged in installation surface 15.
The inside of airtight casing 1 is filled with SF 6arc gas such as (sulphur hexafluorides).The inside of the first explosion chamber 2 and the second explosion chamber 3 has contact (not shown), thereby cuts off the electric current in the power stations such as transformer station, switchyard by opening this contact.Thus, circuit breaker 50 is for possessing the double-fracture circuit breaker of Liang Ge explosion chamber 2,3.In the time opening contact in the inside of each explosion chamber 2,3, to contact ejection arc gas, thereby realize, the electric arc producing on contact is carried out to extinguishing arc.
The first explosion chamber 2 is connected with bonding conductor 4 respectively with the second explosion chamber 3.The first explosion chamber 2 is configured in the side of bonding conductor 4, and makes the axis 12 of the first explosion chamber 2 be approximate horizontal (with installation surface 15 almost parallels).The second explosion chamber 3 is configured in the top of bonding conductor 4, and makes the axis 13 of the second explosion chamber 3 substantially vertical (substantially vertical with installation surface 15).By configuring as described above, connect each explosion chamber 2,3, the axis 12 that makes the first explosion chamber 2 and the axis 13 of the second explosion chamber 3 roughly become the angle of 90 degree.
In addition, the conductor 16 that extend the opposition side of the side that is connected from the first explosion chamber 2, with bonding conductor 4 is derived upward from airtight casing 1, and extends substantially in parallel with the axis 13 of the second explosion chamber 3.In addition, derive the side of the conductor 17 that extend the opposition side of the side that is connected from the second explosion chamber 3, with bonding conductor 4 from airtight casing 1 to first explosion chamber's 2 one sides, and extend substantially in parallel with the axis 12 of the first explosion chamber 2.By making as described above conductor 16,17 derive from airtight casing 1, the conductor 16,17 of deriving from airtight casing 1 can not given prominence in the horizontal direction compared with circuit breaker 50.
Operating means 8 is the devices for switching manipulation is carried out in the contact of each explosion chamber 2,3.Operating means 8 is connected with bonding conductor 4.Each contact is connected with operating means 8 via insulating bar 9, can utilize an operating means 8 to operate the contact of explosion chamber 2,3 simultaneously.Operating means 8 is configured in the below of bonding conductor 4, is clamping bonding conductor 4 with the second explosion chamber 3 and be positioned at the opposition side of the second explosion chamber 3.
As mentioned above, by one of them in Liang Ge explosion chamber 2,3 is configured in to the top of bonding conductor 4, thereby can suppress circuit breaker 50 maximization in the horizontal direction.Thus, can in the power station such as transformer station, switchyard, improve the configuration degree of freedom of circuit breaker 50, and can suppress manufacturing cost.
In addition, by operating means 8 being configured in to the below of bonding conductor 4, thereby compared with being configured in the situation of side of bonding conductor 4, can suppress circuit breaker 50 maximization in the horizontal direction.In addition, can be not outstanding to horizontal direction compared with circuit breaker 50 owing to being configured to the conductor 16,17 of deriving from airtight casing 1, therefore can further suppress circuit breaker 50 maximization in the horizontal direction.
